Is it possible to develop and host a Teams bot using AWS technologies (or any other technology besides MS Azure)? That is, developed using Node.JS and deployed as an AWS Lambda? Has anybody successful(if at all) in doing that? Is there a sample for reference? The available node.js examples seems to be using only ngrok or MS Azure.
Thanks for reply @Bill Bliss. Can a free trial MS Azure account be *safely* used for learning MS Teams bot development, trying out the existing samples and others without getting charged? That is, register a bot as well as potentially host bot in a Windows VM as well for prototyping purposes. Just wanted to be sure.
Also, can "Teams Free" be used for trying out Teams App development? Or is it absolutely required to have an Office 365 developer tenant?
